Showerthought: A painter at the trade show in Reno told me I was blocking panels too dry
I was at the Reno convention back in March and this painter named Dave watched me spray a door for about 10 seconds, then said my overlap was way too tight and I was laying it on dry. I switched to a 50 percent overlap and slowed my pass down, and my runs actually went away instead of getting worse, which sounds backwards. Three jobs later my clear is way smoother and I am sanding a lot less. Anyone else get one tip at a show that stuck with them more than a whole class?

The part about "my runs actually went away instead of getting worse" is the whole thing right there. Dry spray is basically thousands of tiny bumps that never flow together, so your clear sits on a rough surface full of little air pockets. When you slowed down and widened the overlap, you gave the material time to melt into itself, which is why it got smoother and you sanded less. The weird part nobody talks about is how a dry coat makes you think you need more coats for coverage, so you keep piling on dry material and making the texture worse. Dave saved you weeks of chasing a problem that was caused by the fix you thought you needed. Show floors are full of guys selling $400 classes but the best lesson is usually some old painter watching you for ten seconds.
